It can be observed that points (0, 32) and (−40, −40) satisfy the givenequation. Therefore, these points are the solutions of this equation.
The graph of the above equation is constructed as follows.
(ii) Temperature = 30°C
Therefore, the temperature in Fahrenheit is 86°F.
(iii) Temperature = 95°F
Therefore, the temperature in Celsius is 35°C.
(iv)
If C = 0°C, then
Therefore, if C = 0°C, then F = 32°F
If F = 0°F, then
Therefore, if F = 0°F, then C = −17.8°C
(v)
Here, F = C
Yes, there is a temperature, −40°, which is numerically the same inboth Fahrenheit and Celsius.
